EE1 — Brachypodium distachyon

Summary

BdEE1 (BRADI_3G22550V3) on Brachypodium distachyon chromosome 3 encodes an enolase (EC 4.2.1.11) with phosphopyruvate hydratase activity, and is also annotated with RNA folding chaperone, SUMO transferase, and DNA-binding functions. The gene is associated with glycolytic process, cold acclimation, response to abscisic acid, trichome morphogenesis, and embryo development. It localizes to the cytosol, chloroplast stroma, mitochondrial envelope, and plasmodesmata. BdEE1 is linked to grain volume, leaf length, stomatal opening, and low-temperature stress response. Associations with root hair number, trichome development, seed oil content, seed yield, photosynthetic capacity, drought tolerance, lignin content, and senescence have been observed for related enolase genes. Studies of related genes in other species connect the family to freezing tolerance, salt tolerance, seed size, and pollen development.
